MFR-50FRE52-300R

Through Hole Resistors (THRs) are electrical components that introduce electrical resistance into a circuit, which is used to control the electrical current flow. The MFR-50FRE52-300R is a THR that belongs to the Fusible Resistor type. Fusible resistors are specifically designed to overload at certain currents or times and essentially “burn up” or melt. When this happens, the resistor disconnects itself from the circuit in order to protect other components in the circuit from damage that could be caused by high currents.

The MFR-50FRE52-300R is a THR with the following specifications: resistance of 300 ohms, footprint of 5×11 mm (4.3×10.2 mm actual), 0.5W power rating, and ±5% tolerance. The maximum voltage across the MFR-50FRE52-300R should not exceed 50V. This THR can operate within a temperature range of -55°C to +200°C.

The MFR-50FRE52-300R can be used in many different applications depending on the specific requirements of the circuit. For example, it can be used as an inrush current limiter in a low voltage DC circuit and it can also act as an overcurrent protection device in a non-isolated AC circuit. It can also be used in applications where the MFR-50FRE52-300R is subjected to high frequency ripple currents.

The MFR-50FRE52-300R is designed to work with Asymmetric Fusing technology, which ensures that the THR is accurately, reliably and quickly fused even under a high inrush current. This technology also ensures that the MFR-50FRE52-300R is quick to respond to inrush current spikes and immediately breaks the circuit once the current exceeds its specified current limit. As asymmetric fusing technology is used the MFR-50FRE52-300R provides excellent short circuit current limiting performance and enhanced surge suppression.

In conclusion, the MFR-50FRE52-300R is a THR specifically designed to provide overcurrent protection and inrush current limiting performance. It has an asymmetric fusing technology for better response to high inrush currents, and it has a temperature range from -55°C to +200°C. It has a power rating of 0.5W and resistance of 300 ohms. It can be used in applications such as low-voltage DC circuits and non-isolated AC circuits.
